[Server-devel] Backup and Recovery

[Hamilton Chua]

Martin,

Thanks for the confirmation. I am in the process of debugging. The only
change that made it get that far was to the journalentrybundle.py file.

Adding the get_bundle_id def (it just returns  "None" btw) allowed it to
go a step further and unzip the backup file.

However, please see the new error I am getting below. It deflates the
backup file but right after that it errors out complaining about a
missing __zip_file.

I noticed that it assumes the files extracted from the backup data is an
ActivityBundle. Is that correct ?

I'm tempted to just upgrade sugar to 0.86 but there might be those still
using strawberry who are reluctant to upgrade but would like to get
backup and restore working for strawberry, so finding exactly what to
change/fix on strawberry might be useful.
